USB receivers and suspend mode

I bought this the other day and it would not work correctly when I went to resume from a suspend. I also bought the delorme 04 + receiver and it did the same thing. I am just going to sell the USB one and use an old tripmate receiver sice its serial and at least reliable. the newer usb models seem to get pour reception as well. the tripmate isnt as fast or accurate, but it gets better reception and at least works all the time. using stree atlas usa, is there a better product? seems to work ok..
